GlowShift’s Black 7 Series Digital Wideband Air/Fuel Ratio Gauge is essential when tuning any performance vehicle. This digital wideband gauge allows you to closely monitor and tune your car or truck’s air to fuel ratio from 10.0 to 20.0 AFR on a bright blue LED display. With this gauge you’ll have the ability to carefully map out your vehicle’s AFR through the range of engine RPM. Benefits include maximized power and engine performance, higher fuel economy and reduced emissions.

The Black 7 Series
GlowShift’s Black 7 Digital Gauge Series comes standard with a cutting-edge design that includes a black gauge face and low profile magnified clear lens. This gauge only features a blue digital readout, but the trim ring matches the Black 7 Color Gauge Series, assuring that all of your gauges are a perfect match.

Digital Wideband Benefits
With GlowShift’s digital wideband air fuel gauge you’ll experience swift and responsive readings on your car or truck’s air to fuel quality values. These readings are not only provided almost instantaneously, but they’re also delivered with incredible accuracy down to one decimal point. These accurate readouts are one of the many benefits of the digital wideband gauge. The eye-catching digital display will also look great inside of your car or truck, enhancing the interior of your vehicle.

Tri-Color LED Ring
Among the features of this digital wideband gauge is a three color LED ring that indicates rich, lean and optimal values with the corresponding colors green, red and yellow respectively. Each color is displayed at the top of the gauge above the blue AFR readout, depending on which value range is currently being utilized. Features such as this Tri-Color LED Ring were included in the design with the goal of giving you the best wideband gauge possible.

Rich: 10 ~ 12.9 AFR | Optimal: 13 ~ 17.9 AFR | Lean: 18 ~ 20 AFR

  • Pfft hell yea

    Posted by Tyler on May 16, 2020

    So received this as a Christmas gift for my soon to be turbo build and had it in the package until about March. I was real excited to get it in the car and tune it until i look at the gauge and it just reads 18.5 no matter what. I thought to myself hmm maybe the sensors bad and I unplugged it and still nothing. After multiple conversations with Tech Support it was pretty much agreed upon to be the controller. I have been waiting 2 months to "ship the controller in for inspection" due to this stupid COVID-19 so here I am stuck with a defective product that was BRAND NEW!!! Next time will go AEM and spend the extra dollar.
